soil quality and degrading the environment which hampering balanced ecosystem. The use of pepper residues as an organic amendment improved biochemical properties of the soil with positive effects on broccoli quality and had no negative impact on yield. We investigated the effects of integrated organic and inorganic fertilizers on the growth and yield of indica rice variety Manawthukha ... has become popular. Effects of Farmyard Manure and Inorganic Fertilizer Application on Soil Physico-Chemical Properties and Nutrient Balance in Rain-Fed Lowland Rice Ecosystem 310 . The experiment aims to separate the soil into different water stable aggregate size fractions in order to look at the stability of the soils as well as the carbon and nitrogen stabilized in the fractions as affected by organic and inorganic fertilizers. availability of livestock in the country, necessitates the use of integrated nutrient management. The effects of the organic amend-mentswereobservedevenwhentheyinvolvedasmallportion of the total amount of nutrients supplied; thereby confirming that some of the beneficial effects of integrated fertilizer strategies may occur in the short term. Improper use of inorganic fertilizer, herbicide and pesticide for the crops are not so good for health as well as for environment. Effect of organic and inorganic fertilizers on yield and quality of ruzi grass (Brachiaria ruziziensis) grown on saline sandy soils of the Northeast, Thailand Panchaban, S.1; M. Ta-oun1 and S. Sanunmuang1 Keywords: organic fertilizer, inorganic fertilizer, ruzi grass, saline soil, sandy soil Abstract Most soils in the Northeast of Thailand are sandy in texture. CP has great potential in rice cultivation, where it can serve as a soil fertilizer to supply nutrients for uptake by plants (Binh and Shima, 2018).
fertilizers were maintained at similar levels to those obtained with inorganic fertilizer. However, this practice has not yet been tested in rain-fed lowland rice For this purpose, two growth periods of oat ( Avena sativa L.) were studied under tropical conditions (26°C and 2600 mm annual rainfall) on an infertile sandy soil in the greenhouse in fivefold replication. In this study, taking typical red soil in Qiyang area of Hunan Province as an example, the results of a 20-year field experiment to investigate are described how long-term application of organic fertilizer improves crop yield through increasing organic matter content and decreasing soil acidification.

Effects of chemical fertilizers on soil are great and irreversible. Long-term use of chemical fertilizer can change the soil pH, upset beneficial microbial ecosystems, increase pests, and even contribute to the release of greenhouse gases.
Therefore, the objective of this study was to test whether biochar effects on soil quality and plant growth could be improved by addition of mineral and organic fertilizers. When the soil sample soaks for five minutes, it mimics the slaking process occurring in the field upon rainfall.
